Design, Construction, and Maintenance of Highway Safety Appurtenances and Features (1-Day)
Instructor-led Training (ILT)
TRAINING LEVEL: Accomplished
CLASS SIZE: Minimum: 22 Maximum: 30
The course has been developed for a 3-day course presentation but can also be structured into a 1- or 2-day training course. The sponsoring agency will be able to choose the modules for presentation that will best meet its needs. The course covers the design, construction, and maintenance of highway safety appurtenances and features. It covers the purpose and performance requirements of state-of-the-art highway safety features, such as breakaway sign supports, breakaway utility poles, traffic barriers, impact attenuators, traversable terrain, and hardware features such as drainage inlets. The course describes how these features function, what can go wrong, and how to recognize and correct improper installations.
Upon completion of the course, participants will be able to:
Identify advantages and disadvantages of different types of longitudinal barriers and crash cushions
Identify National Cooperative Highway Research Program 350 tested safety appurtenances
Identify application of highway safety appurtenances, why they are used, when and where they should be used, and what is necessary to ensure their function
Design the placement of, and determine the need for, longitudinal barriers
Use required installation, construction, and maintenance procedures for proprietary longitudinal barriers, terminals, transitions, crash cushions, bridge railings, and sign supports
Recognize substandard or potentially hazardous highway appurtenances and features
Develop alternatives to eliminate, correct, or mitigate unsatisfactory operational characteristics of existing safety devices
Highway engineers, including local personnel involved in the design, construction, or maintenance of highway safety appurtenances and features. This course is suitable for all local, State, and Federal employees that are involved with the installation and repair of highway appurtenances.
